Nephrostomy is used for diagnostic purposes including assessment of renal function and urine culture. Which additional purpose does it serve?

• A. IV fluid administration
• B. Brush biopsy
• C. Blood transfusion
• D. Urinary stenting

Answer: (B)

Nephrostomy serves multiple purposes in clinical practice, particularly in managing urinary tract issues. One of its additional purposes is urinary stenting. While nephrostomy primarily involves placing a tube to drain urine directly from the kidney when there are obstructions, it can also facilitate stenting to ensure that urine can flow adequately from the kidney to the bladder.

Urinary stents, often used after procedures to keep the ureter open, allow for proper drainage and reduce the risk of complications such as kidney damage from prolonged obstruction. Therefore, in a clinical scenario where a nephrostomy is in place, it can be part of a larger strategy to maintain urinary tract patency and protect renal function.

The other options like IV fluid administration, brush biopsy, and blood transfusion are not directly associated with the purpose of nephrostomy. IV fluids are typically administered systemically rather than through a nephrostomy tube, brush biopsy is a diagnostic procedure that involves direct sampling from tissues, and blood transfusions pertain to hematologic management rather than renal drainage or assessment. Thus, urinary stenting aligns with the use of nephrostomy in managing renal function and urinary flow effectively.
